Production
Lanthanum hydroxide can be obtained by adding an alkali such as ammonia to aqueous solutions of lanthanum salts such as lanthanum nitrate. This produces a gel-like precipitate which can then be dried in air.
Alternatively, it can be produced by the action of water at 90 °C on metallic lanthanum.
